> For sake of service protection we should not give absolute trust to clients regarding
resource limits that can impact stability, like cell size limits. We should add a server side
configuration that sets a hard limit for individual cell size that cannot be overridden by
the client. We can keep the client side check, because it's expensive to reject a RPC that
has already come in.
